Fifteen, count 'em, fifteen human body parts that will disappear one day.
If you ever thought that all people are built the same, think again.
If you thought that all our body parts are vitally important
*Buzzer noise*
Wrong answer.
In the first part of the Descent of Man, Charles Darwin identified roughly a dozen body parts
that he gleefully described as "Useless or Nearly Useless".
Darwin's catalog was far from complete. Our bodies are littered with the parts we don't need.
So, we've prepared a shocking list of 15 body parts that will disappear in the future!
Give us a thumbs up and keep watching
That is, if you don't lose your thumbs
*laughing*
Counting down from number 15: body hair.
Body hair used to protect humans from severe weather conditions.
But what about now? When we have our cozy, woolen sweaters and leather jackets.
Well apparently, most hair on the human body serves no function
So, it is very likely to get extinct in the future.
Besides brows perhaps, they keep the sweat from our eyes.
And the male facial hair plays a significant role in attracting the opposite sex,
So they tell me.
and we have alot.
frontal, ethomoidal, sphenoidal, maxillary sinuses
oi, in fact, no one knows why we have these troublesome muscus lying cavites.
perhaphs to make the head lighter?
mmm, probably its snot
number thirteen: extrinsic ear muscles
Some animals rabbits, and dogs for example
Can move their ears independently
How does this happen?
Thanks to these exotic sounding muscles
But, do you know what? People also have them. That's why some gifted individuals can wiggle their ears.
Don't envy these muscles serve no purpose.There is just one fact.
They react to positive emotions. Though nobody understands why.
#12: Wisdom teeth
*Intense grunt* OhhOho This pain, this bother. Why does our bodies have to grow them.
Just to have them pulled out later
Well, Its simple! Because Dentist have to pay for their books.
Well actually, its obvious that early humans had to chew plants. In order to get enough calories to survive
But these days only about 5% of the population has set of these..Let us be honest. they're useless teeth
What's more, as human jaws have become
smaller in the process of evolution the rest of the people simply don't have
space in their mouth for these teeth back in the days when toothpaste didn't
exist they were kind of backup grinders but nowadays we hope they will be the
first to disappear from the list
number eleven: neck rib have you never heard about neck ribs oh boy it's a
set of cervical ribs possibly a leftover from the age of reptiles they still
appear in less than 1% of the population some people have such a rib only on
their left or right side while some have both they often cause nerve and artery
problems maybe that's the reason why most people who have them get them
removed
number 10 Paul Morris muscle
there is a long narrow muscle running from the elbow to the rest it is already
missing in 11% of humans today so it's a safe bet that with time it will
disappear completely once it was important for hanging and climbing but
nowadays let's face the truth unless you're a martial artist or a rock
climber you wouldn't care or even notice if it disappears
number nine male nipples first of all that is the question why do both men and
women have nipples well it is quite curious in the early stages of fetal
development an unborn child is effectively sexless or without gender
thus nipples are present in both males and females men generally lack the
necessary levels of prolactin to stimulate lactation and so cannot
produce milk but there are exceptions to this rule
number eight arrector pili muscles
did you know that these are the small muscles that allow animals to puff up
their fur for insulation or to intimidate others gotta see my dog ever
seen your cat looking like a porcupine it's them these muscles are working
they're meant to ensure that an animal seems larger than it is therefore there
is a higher chance to scare the enemy away now it's time for a surprise humans
have such muscles - goosebumps are the indicator of them at work we get them
when we're frightened amazed or cold apparently we've lost most of the fur
and acquired warm clothes we don't need any additional protection from freezing
temperatures or the source to intimidate our rivals anymore these days we use
cars for that therefore it's likely that these muscles
will disappear with time are you enjoying this video so far remember to
hit the like button when we're done but wait there's more to come
number seven appendix
why do we need it at all this narrow muscular tube attached to the large
intestine served its purpose many centuries ago it was a special area for
digesting cellulose when the human diet consisted more of plants than animal
food but what about now some research shows that this part of our body can be
in fact useful it might store special bacteria good for those who suffer from
diarrhea anyway the appendix may inflame and lead
to appendicitis this is considered one of the most widespread emergencies an
immediate operation is typically needed but it can be done through laparoscopic
surgery and only take about eight minutes by the way did you know that
according to research men are more prone to having appendicitis than women
number six 13th rib
our closest cousins chimpanzees and gorillas have an extra set of ribs what
about humans most of us have 12 except for 8 percent of adults they have an
extra one (thats it)
number five coccyx
oh you've never heard of coccyx yeah it's a great rock band no no what about
its other name a tailbone it's all that is left of the tail that most man will
still use for balance and communication what's more there have been 100
documented cases of babies who were born with a tail which of course makes it
challenging to buy pants anyways what is the purpose of a tail bone there is not
well several muscles are attached to this point and it does help us support
ourselves when we sit down and lean back however it's not vitally important
number four third eyelid
a third eyelid you will ask do we have it yes we humans retain a tiny fold in
the inner corner of the eye it is what is left of a membrane birds and mammals
have had for protecting the eye and sweeping out debris at the same time
providing visibility we don't need this function anymore most of us are wearing
glasses so it's a high possibility that it will disappear with time number three
Darwin's point
it is a small folded point of skin toward the top of each year that is
occasionally found in modern humans and many Vulcans it may be a remnant of a
larger shape that helped focus distant sounds
nowadays only 10% of people have this greeting from the past but there is a
theory that many more are the carriers of the gene responsible for its
appearance it just doesn't show anyway with all the modern technologies used
for enhancing hearing it's no wonder that is becoming extinct
number two subclavius muscle now this is a small muscle that stretches under the
shoulder from the first rib to the collarbone it would be beneficial if
humans were still walking on all fours it's not the case but some people still
have one some have none and there are a few who have two and number one toes yes
you heard correctly scientists have found out that humans used to walk in
balance more in the middle of their feet but now we have gradually transferred to
balancing more on the side of our big toe studies also show that our centre of
balance is still shifting inward so in fact this means that humans used to rely
on their toes for balance but now they don't use them as much if this trend
keeps up we will no longer need our toes and when you're playing with your infant
baby's foot you'll be going this little piggy went to the market and hey where'd
everybody go do you think this future is a likely one share your opinion in the
comments and share this video with your friends they need to know what to expect
in the future tell them it's happening next week join
